Why my Fn F5 doesn’t work Asus laptop?

Answered by Antonio Sutton

There could be several reasons why the Fn+F5 combination is not working on your Asus laptop. Let’s explore some possible causes and solutions:

1. Fn lock: As mentioned earlier, some laptops have a Fn lock feature. This means that pressing the Fn key will activate the secondary functions of the F1-F12 keys, rather than the primary actions (such as adjusting brightness or volume). To check if the Fn lock is enabled, try pressing just the F5 key without the Fn key. If that works, then the Fn lock is likely the issue. Pressing the Fn key along with the F5 key should toggle it back to its default functionality.

2. Keyboard driver issues: Outdated or corrupt keyboard drivers can cause keys or key combinations to stop working. To resolve this, you can try reinstalling or updating the keyboard drivers. Here’s how you can do it:

– Go to the Asus website and navigate to the “Support” or “Downloads” section.
– Enter your laptop’s model number and search for the latest keyboard drivers compatible with your operating system.
– Download the driver files and follow the instructions provided by Asus to install them.

After the installation, restart your laptop and check if the Fn+F5 combination is now working.

3. BIOS settings: Sometimes, the Fn key behavior can be altered in the BIOS settings. You can try resetting the BIOS to its default settings to see if it resolves the issue. Here’s a general guide:

– Restart your laptop and repeatedly press the “F2” or “Del” key (or the key specified by Asus) to enter the BIOS setup.
– Look for an option related to the keyboard or function keys.
– If there is an option like “Fn key behavior” or “Function lock,” make sure it is set to the desired mode (e.g., “Function key first” or “Enabled”).
– Save the changes and exit the BIOS setup.
– Restart your laptop and test the Fn+F5 combination.

4. Hardware issues: If none of the above solutions work, there might be a hardware problem with your laptop’s keyboard. In such cases, it is recommended to contact Asus customer support or take your laptop to a certified technician for further diagnosis and repair.

Personal experience: I once encountered a similar issue with my own Asus laptop. The Fn keys stopped functioning properly after a system update. After trying the above steps, I realized that the keyboard drivers were not fully compatible with the new update. Updating the drivers to the latest version provided by Asus resolved the problem for me.

Remember, these are general troubleshooting steps, and the specific steps or options may vary depending on your laptop model and operating system. It’s always a good idea to refer to the user manual or consult Asus support for accurate instructions tailored to your device.
